Ever heard of #faculae and #swirls, or #spicules, dynamic #fibrils, #jets, #jetlets, and #campfires? These are the phenomena that ISSI International Team #604 “Small-scale eruptive events in the Sun” is studying! Read more about their project on: teams.issibern.ch/small-scalee...

Cold plasma in the Earth’s ionosphere and plasmasphere plays a critical role in near-Earth space, driving wave-particle interactions, coupling processes, and radio wave propagation. ∿ ∿ ∿ See what ISSI Working Group ‘ATIP’, led by Artem Smirnov and Fabricio Prol, is up to: collab.issibern.ch/atip/ 🔭

You search for your keys, don't find them, and assume they're lost …until they turn up in yesterday's coat. That's a false negative. Our new Highlight digs into the blind spot the field has quietly underweighted for decades 👇 www.issibern.ch/the-hidden-p... #Astrobiology #SpaceScience 🔭

The shape of the heliosphere, the bubble formed by the solar wind as the Sun moves through the galaxy, is currently being debated – in particular the looks of its tail. The ISSI Int. Team #613 led by Marc Kornbleuth is tackling this critical problem. ☀️ More: teams.issibern.ch/particleacce... 🔭

Where does the Electron Superhalo, a faint but ever-present population of unusually energetic electrons in the solar system, come from? ☀️ ISSI Int. Team #656 led by Domenico Trotta tries to uncover exactly that. Read more: teams.issibern.ch/superhaloeni...

Evolution of the Solar System: Constraints from Meteorites How did our Solar System form and evolve? This new volume edited by D. Hezel, H. Palme, K. Mezger, A. Morbidelli & J. Zipfel, brings together leading experts to explore exactly that.

🔭 How do solar energetic particles travel from the Sun to Mars' surface? This week's International Team is modelling this journey - through the heliosphere & Martian atmosphere - to support future Mars missions & improve radiation risk assessment. Read more: teams.issibern.ch/solarparticl...

🔭 This ISSI Team - led by G. Thomas - is developing new techniques to homogenise large spectroscopic surveys onto a common scale – essential for studying the Milky Way as a whole (e.g. combining Northern & Southern hemisphere data). Discover more teams.issibern.ch/asteroshop/

What do the chemical abundances of distant galaxies tell us about the stars that made them? 🌌🔭 This week at #ISSI, experts including Allison Strom, Danielle Berg, Corinne Charbonnel, Brian Welch, and Antonella Nota are meeting to ponder this question! workshops.issibern.ch/distant-galaxies

While at the @eas-meeting.bsky.social we met the daughters of the great Swiss astronomer Fritz Zwicky, who in 1972 was awarded the @royalastrosoc.bsky.social Gold Medal. Margrit Zwicky and Franziska Pfenninger-Zwicky stopped by our stand to say their father was "absolutely delighted" by the award.

Hey #EAS2026 community! If you are in Lausanne this week, stop by the ISSI booth and say 'Hi'! Whether you are curious about the research opportunities, looking for collaborations, or just goodies, come find us on the blue carpet! 🟦 @raducan.bsky.social @fabiocrameri.ch
